JOHN TAMBERIIN, OF PHILADELPHIA,PENNSYLVANIIL ASSIGNOR TO THE GEORGE W.BIABON COMPANY, OF'PI-IILADELIHIA, PENNSYLVANIA, A CORPORATION OFPENNSYLVANIA.

SHEET-LINOLEUM DISINTEGRATOR.

Application filed November 2, 1920. Serial No. 421,278.

This invention is a machine designed primarilyV for disintegratingsheets of linoleum fromwhich shapes have been punched for making inlaidlinoleum, but it will be understood that it is not limited to operationupon sheets of this character.

The invention is characterized by a revoluble member (as a cylinder)provided with projecting devices (as rearwardly bentfmgers) spaced alongthe axis of revolution; a set of downwardly projecting stationarydevices (as fingers inclinedat a small angle to the vertical) spacedalong said axis of revolution so as to be passed in alternating relationby the devices first named; a chute extending downwardly from thepunching machine for carrying the sheets to be disintegrated over thedevices second named where they are engaged in shearing relation by therevolving devices first named; stationary projecting devices orstrippers spaced along vsaid axis of revolution in alternating relationto the devices rst named and adapted for disengaging the broken ordisintegrated material ytherefrom and from the cylinder, and meanscomprising a. conveyer for carrying away the broken material. Y

This mechanism, in the preferred practice, is combined with mechanismthrough which sheets are fed and by which shapes are punched therefrom,as in the manufacture of inlaid linoleum, the shapes being removed fromthe sheets and the remainder being fed down the chute to thedisintegrating mechanism.

The invention is embodied 1n the mechanism set out in the followingdescription and the accompanying drawings in illustration thereof.

In the drawings, Fig. 1 is a sectional elevation of mechanism forfeeding and punching linoleum sheets in combination with my improvedmeans for dismtegratrng and removing the punched sheets; Fig. 2 is apart sectional plan view taken on the line 2-2x of Fig. 1, and Fig. 3 isan irregular sectional view taken On the line 3X-3X of Fig. 1.

1n the machine illustrated, the linoleum sheet 1 is movedintermittently, `over a perforated stripper plate 2 and beneath atemplate 3, between the block 4 having the dies 5 thereon and the head6. The movements of the sheet are effected by known carrier mechanismcomprising the endless belts 7 which pass over the wheels 3, 9 and 10,the latter being driven by a sprocket wheel 11 fixed thereto, a sprocketchain 12 passing thereover, a sprocket wheel 13 over which the chainpasses, a pinion 14 fixed to the wheel 13 and a spur wheel 15 whichdrives the wheel 14 and the carriage 15 having grippers 15a'and 15b forengaging the sheet.

The block 4 is elevated by the rotary cams 16 which are connected tooperate together by the meshing spur wheels 17 and act on rollers 18 onthe block. The plate 2 is caused, by the elevation of the block, topress the sheet lagainst the,4 template 3, and the template (carried bythe bolts 19 movable in the frame 15') is carried thereby against theframe. The dies 5 punch the desired shapes lfrom the sheet by passingtherethrough, forcing the shapes into the corresponding apertures in thetemplet. Thereupon the block 4 falls by gravity as the cams 16 arerevolved further, the plat-e 2 stripping the perforated sheetfrom thedies 5 as they are withdrawn.

The punched section of the sheet 1 is fed down the steeply inclinedchute 20 into a box 21 through its top aperture 21.

A bar 22, which is disposed across the aperture at the bottom of thechute, is provided with the spaced downwardly extending projections orfingers 23 inclined at a small angle to the vertical and over which besubstantially parallel to the fingers 23V in passing them and shall acttherewith in shearing relation, instead of pulling and tearing thesheet; theends of the revolving ngers acting in shearing `relation tothe bar 22 as well as to the fingers 23.

A bar 26, supported in the box 21, has

fingers or strippers 27 fixed thereto in spaced relation so that thefingers 25 shall pass between them in alternating relation, thestrippers detaching broken linoleum adhering to the cylinder 24 and thefingers ,25, Y

The disintegrated `linolenm,` which 'tells from the cylinder and thefingers 25, passes between the :traine members 2S and frills upon thechute 29, which delivers it,I Within the box, to `the travelling belt orconveyor 30, the hitter running through the aperture 2l in the side ofthe box.

The cylinder' 2l and the belt 30 are opel ated in unison from thejournzilled shaft 31 having1 thereon the spur wheel 32 end the sprocketWhee 33. The Wheel `3Q drives n pinion 34 lixed to the cylinder 24. 'Whesprocket Wheel 33 drives n chain 35 which puisses over a sprocket wheel3G, the hltterbeingtixed to n journalled shaft 37 having lixed thereon apulley 38 over which passes the belt 30.

Having described my invention, I claim:

1. In a machine ot' the character described, the combination of a sheetconveyor, e s1otted member to which :rsheet is delivered by seidconveyor`y and :i distintegrator comprising a revoluble member havinglingers movable through the slots in said slotted member, said fingersbeing so shaped as to engage a sheet on the slotted member substantiallyat right angles to the surface thereof, said slotted member andrevolnble member cooperating` to sheer the sheet Without substantialpull thereon longitudinally.

In a machine ot the character described, the combination ol a chutehaving e bnr adjacent the mouth thereof with spneed downwardlyprojectingr fingers thereon, ai revoluble member having lingers thereonmovable between the lingers first named, seid revoluble tingers beingrbent reznwardly with relation to the direction oit their revolution andharing their sheet engaging parts substantially parallel to the lingersfirst .named in passingr them, e stripper having .fingers through whichsaid reif olnble fingers pees, and` :i conveyor to which materialdisintegrated by snidfingers is discharged.
